    Wait

    Open valve. Let drain completely.

    Brew complete.

Notes

The key innovation is using two different water temperatures. The initial hot pours (98°C) with valve open extract bright acidity through percolation. The final cool pour (70°C) with valve closed adds body through immersion without harshness. Adjust cooler water temp between 60-80°C to taste.
